Hello, I have tried using your code.
The rendering effect is excellent and the efficiency is very high.
After attempting to drag the column width (to the maximum width), when clicking to select the entire row, there will be a problem of positioning deviation.
It's not certain whether it's a problem or not.
The picture below shows the test situation.
